A seal assembly is disclosed. The seal comprises a metal spring bonded to an elastomer body that is coupled to a polymer ring. The spring may comprise a cantilevered, overlapped metal strip. The elastomer and polymer mechanically interlock with radial members. The elastomer has contacting surfaces configured in outward extending radii to enhance forward edge loading and oil removal from the dynamic surface. In hydraulic service, the seal prevents the egress of hydraulic fluid and ingress of foreign particles.
